| titleOfInvention | Heat treatment method for biaxially stretched polyester film |
| abstract | (57) [Summary] (Modifications) [Problem] To provide a heat treatment method for a biaxially stretched polyester film capable of efficiently obtaining a biaxially stretched polyester film having good flatness and excellent thermal dimensional stability. SOLUTION: In the method for heat-treating a biaxially stretched polyester film, the temperature of the suspended film is made to reach a maximum temperature Tmax shown in the formula (1) while running the film from a preheating roll to a cooling roll. The film is relaxed by over-feeding the film, and the film is cooled in two stages by two cooling rolls. Tg + 50 ≦ Tmax ≦ Tg + 150 Equation (1) (In Equation (1), Tmax is the maximum film temperature (° C.), T g is the second order transition temperature of polyester (℃) |
